| 内容提要 | 节能减排是我国经济高质量发展的重要环节。本文从非参数生产经济理论出发，基于共同边界方法和两期方向距离函数来克服技术异质性与不可性解问题，同时利用Bootstrap方法增加非参全要素生产率的统计推论，相对于传统方法，提出了一种全新的全要素生产率测算及分解框架。然后，将其应用于我国主要火力发电企业的面板数据来分析其碳全要素生产率的变化及其源泉、节能减排效应分析。研究发现：2008年后，我国政府制定了更有约束的节能减排目标和2100亿的低碳技术创新投资，导致火力发电厂整体的碳全要素生产率水平大幅上涨；人力资源水平仍然是制约着我国火电企业碳全要素生产率提升的重要因素，在推动火力发电厂节能减排中还需进一步解决人才管理体制，并为低碳技术创新改造提供支持；我国火力发电企业内部存在异质性，2008年后节能减排目标和低碳技术创新投资刺激计划对不同类型的火电厂存在非对称影响。 |
| Abstract | It plays an important role in the high-quality development of China for the policy on energy saving and emission reduction. Based on the nonparametric production theory, this paper presents a very innovative theoretical framework to investigate the dynamics of carbon total factor productivity and its decomposition, and applies it to a panel data of Chinese thermal power plants to analyze the effects of energy saving and emission reduction. It adopts metafrontier and biennial directional distance function to overcome the problem of technology heterogeneity and infeasibility, and further uses the bootstrap method to make statistical inference on the nonparametric total factor productivity, showing performing characteristics comparing to the traditional one. The results show that the carbon total factor productivity of whole thermal power plants has significantly increased after 2008 for more binding targets on energy saving and emission reduction and 210 billion yuan investment on low carbon technology innovation. The human resources have hindered the improvement on the carbon total factor productivity of Chinese thermal power plants and urgently need to reform on its management. Moreover, there is heterogeneity in Chinese thermal power plants for asymmetric effects of more binding targets on energy saving and emission reduction and 210 billion yuan investment on low carbon technology innovation after 2008. |
